Monogamy is a relationship structure where an individual has only one partner at a time. This practice is common in many cultures and is often associated with romantic relationships, where emotional and sexual exclusivity is emphasized. Monogamous relationships can be formalized through marriage or informal agreements between partners. In contrast to polygamy, where individuals may have multiple spouses, monogamy focuses on a single partnership. This arrangement can foster deep emotional connections and stability, but it may also present challenges, such as the pressure to meet all of a partner's needs.
